How much hanging weight can a 2×4 hold?

A 10 foot long 2×4 carrying a uniform load of

40 pounds per foot

will have a maximum bending moment at the center of the span. A maximum bending moment of 500 ft- lbs can be experienced by a 10 foot long 2×4 with a point load of 400 lbs at the center.

Is a 2×4 stronger on its side?

To be accurate — the

2×4 is the same strength regardless

of how you orient it, just that it will be seeing a lower maximum bending stress if oriented on edge, when loaded as you described.

Can a 2×4 be load bearing?

If it’s a solid 2×6 or greater turned vertically going from the jack stud on one side to the other, there’s a good chance the wall is load bearing. If there are only cripple studs on a flat 2×4 to give you something to attach the drywall,

it likely isn’t load bearing

.

(400 lbs total load) will have a maximum bending moment at the center of the span of 1000 ft-lbs. The same 10 foot long 2×4 with a point load of 400 lbs at the center will experience a maximum bending moment of 500 ft-lbs.

What is the strongest 2×4 wood?

Grown throughout the southeastern U.S.,

yellow pine

is by far the strongest softwood on our list. It has the highest bending strength & compression strength of any softwood seen throughout North America. And it’s high strength-to-weight ratio makes it popular for building trusses and joists.

Can 2×4 be used for floor joist?


It should be OK

, but I’d go closer than 16′′ OC. 2x4s are cheap. another option might be to put plywood below the joist as well as above. This would make the plywood the stressed member and the 2x4s would be acting more like the webbing of an I beam.

Is 2 2×6 or 1 4×6 stronger?

A

4×6 joist is theoretically stronger than a doubled 2×6 joist

because it’s 1/2′′ thicker, but the actual strength depends upon the knots and other inherent weaknesses of any particular piece of lumber (#2 lumber can have some nasty spike knots or large not-so-tight round knots or wane).

Your statement about

2- 2×4 not being as strong as one 2×8

or one 2×10 is technically correct because the height is different for each one (not apples to apples). Referring to the code tables is a little misleading. Double stacked beams (not glued together) each carry half the load.
